VARIABILITY MONTH-CATEGORIES PAGE

MONTHLY DATA VARIABILITY FOR  EACH CATEGORY AND SUB CATEGORY, IN THE YEAR

in all item type views, data are about:

  • expense
  • n° of purchases
  • n° of days of purchase

 

tap on any card, to switch item types

no past data:

  • it can be shown for the most recent year of expense only
  • the item had expense only in the most recent month of expense

only past data are considered, and the most recent month of expense is regarded as the current month

if, an item had expense only in some of the past months, each month with no expense  is taken into account for the calculations, with an expense of zero

 

the red line in the center of the bar graph

it represents the average (for example the average monthly expense)

the length of the green bar

for example for expense, it represents, how much, on average, the actual monthly expense differs from the average monthly expense, as a percentage of the average monthly expense

  • for food, that data tells that the monthly expense, on average, is between 65.47 minus 93.17% of 65.47 and 65.47 plus 93.17% of 65.47 (or, between 65.47 minus 61 and 65.47 plus 61; range: $4.47 – $126.47)
  • the shorter the bar, the less variable, on average, the actual data in each month from the average (the less, on average, the monthly data changes from month to month)
  • if Var% is over 100%, the bar length doesn’t change

only if Var% is very low, it’s safe to say that (for example for expense):

  • each month you spent, more or less, the amount at label Avg and that, that amount changes very little from month to month
  • if your spending habits don’t change over time and barring unexpected events that affect your spending, the average monthly expense is a good predictor of how much you’ll spend, more or less, in the future months;

for food, for example, the average monthly expense is useless: you can’t say that every month you spent, more or less, $65.47 on food

for example, you know your monthly expense for essential needs, is very stable, and your spending habits are very stable:

  • you can spend more on non essential items
  • you can invest more

 

the n° of months where the item has expense:

  • it tells you whether the item is frequent or not in the year, over the months (for example, for apparel, 4/11, means you spent money on apparel in 4 months (January, April, June, November) out of 11 past months in the year)

say, you removed some sub category from consideration, for example, some exceptional expense, because you want to know the variability of your ordinary expense :

  • you can highlight the bar graph for the categories with removed sub categories, by tapping the pencil icon, to find all the categories with removed sub categories
  • and then tap the globe icon
  • and you’ll see the variability of the category’s ordinary monthly expense

 

you can tap the list icon, to show average and variability data, for the sub categories removed from consideration
